SAW TEMPERING AND STRAIGHTENING" MACHINE.

SPECIFICATION forming part of Letters Patent No. 363,296, dated May 17, 1887.

- Application filed February 23, 1886. Serial No. 192,855. (No model.l

To all whom it may concern:

Be it known that I, ALBERT MAEULEN, of the city of Indianapolis, county of Marion, and State of Indiana, have invented certain new and useful Improvements in Saw Tempering and Straightening Machines, of which the following is a specification.

My said invention relates to that class of machines by which saws are tempered under pressure between parallel surfaces and are thus straightened at the same time; and it consists in the various improvements in such machines, hereinafter particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure l is a view of a machine embodying my said invention, partially in front elevation and partially in longitudinal section, the brick-work which surrounds the machine being omitted; Fig. 2, a transverse vertical sectional view through the machine and the surrounding masonry on the dotted line 2 2 in Fi 1; Fig. 3, a longitudinal section, on an enlarged scale, of one of the tempering-blocks on the dotted line 3 3 in Fig. 4; and Fig. 4, a transverse section of the same on the dotted line 4 4 in Fig. 3.

The machine consists, essentially, of a series of blocks having flat straight surfaces, the upper series of which are held stationary from a supporting upper plate and the lower series of which are supported by a lower plate, one

of said series of blocks being adapted to be moved toward the other by a hydraulic or other press, and means for supporting the plates to which these blocks are connected or upon which they rest and of keeping them sufficiently cool to prevent warping, notwithstanding the excessive heat applied directly to said blocks.

It further consists of details of construction 'in said blocks and the supporting and carrying parts and in asystem of dampers for reguchine 5 O, the upper supporting-plate, to which tering the bolt-holes.

the upper temperingblocks are suspended; D, the lower supporting-plate,carrying the lower tempering-blocks; E E, said upper and lower tempering-blocks, respectively, and F a sawplate in position as when being operated upon.

The masonry A surrounds the operating parts in this machine, as shown, and contains the furnace A, ash-pit A and flue A as Well as a pit for the press, all as indicated in Fig. 2.

The columns B connect the upper supporting-plate (which also forms the head of the press) to the lower portion of the press, as shown, and, as will be readily understood, receive the strain when the press is put in operation.

The supporting-plate 0 forms the upper portion of the press and also of the machine proper. It has flanges c upon its sides, as shown,which serve as the sides of water-ways,

and also large stiffening ribs or flanges O, for

I through which the bolts which secure the tempering-blocks thereto pass. These bosses extend above the surface of the water, which flows along over the top of this supportingplate, and thus prevents the water from en- As before indicated, a stream of water is kept flowing over this plate, to keep it sufficiently cool to prevent it from warping or springing. A pipe, 1), is shown as leading the water thereto, and a pipe or any other means may be provided for its discharge.

The constant flow of water provided by this arrangement is a superior means of effecting this purpose. The strengthening ribs 0 are reenforced by tierods c", which extend from the apex of said ribs to the ends of the machine, near where the columns are secured to the plates. They are provided with nuts 0 upon their lower ends, as shown, by which any desired degree of strain may beimparted thereto.

The lower plate, D, is of similar construction to the plate 0, but of course is reversed in arrangement. A pipe, 1), is provided, which conveys the water to the water-way in the surface of this plate provided therefor. Several upwardly-projecting ribs, d, extend up from this plate through the water to the blocks E, which they support, and flanges 0, similar in character and purpose to the flanges are arranged, as it moves down by the power.

from the press being released, to rest upon tracks or ways a provided therefor. means, by disconnecting this portion D from the press, it can be moved in and out of the furnace, as desired.

The blocks E and E are secured to the plates 0 and D, respectively, and apertures are formed through said blocks,through whichthe products of combustion pass from the furnace to the flue. These blocks, as shown most plainly in Fig. 1, are arranged to overlap'e'ach' other or break joints, and thus serve a better purpose while operating upon the saw-plate than if'the joints were one directly above another, thus leaving a portion of the saw-plate wholly exposed. The apertures through these blocks are preferablyprovided with an asbestus or other equivalent lining, e, which is secured therein (either by a dovetail formation, as shown most plainly in Fig. 3, or otherwise) 1forthe usual purposes of a fire-proof lining.

As will be noticed, particularly by an examination of Fig. 2, one set of the'temperingblocks is provided with a flange which passes by'the end of the other and thus shuts off any. passage for the products of combustion that might exist between said blocks, and thus keep said products of combustion from direct contact with the saws. Said blocks are also flanged to pass up and down past the corners of the supporting-plates, upon which they are mounted, respectively, for like rea; sons and purposes, said blocks and also the plates'O and D being cut away somewhat to reduce the bearing surfaces, thus leaving spaces between them, which serve to some extent as air-passages, through which air may circulate and thus assist in keeping said plates 0 and D cool, the spaces between the upper blocks, E, and plate 0 being directly between the metal surfaces of said parts, (see particularly Fig. 2,). while the spaces between the blocks E and plate D are partly occupied with water, and thus the air is between said water and the lower surfaces of said blocks when the wateris used as contemplated. While I the saw-tempering blocks E are secured to the supporting-plate G by bolts, this is not necessary in the lower blocks, E, which rest upon the supporting-plate D by gravity; but it is necessary to provide some means for preventing them from moving about on their bear ings. I have therefore tapered their lower corners somewhat, and inserted between them ribs d which are secured to the supportingplate D by bolts, as shown, and these prevent any movement of these tempering-blocks on said plate. Opposite each of the apertures throughthese blocks in the flue is arranged a,

damper, E", and by the proper adjustment of these dampers the passage of the products of combustion through the apertures can be con- By this.

trolled, and the tempering-blocks thus maintained at an equal temperature throughout. This flue A in which the dampers are located, of course communicates with the chimney or smoke-stack, and thus the required draft is obtained. p

The saw-plate 'F is shown in position between the tempering-blocks, as when being operated upon. v r I am aware of the invention of Elias 0. Atkins, as shown and described in Letters Pat ent No. 250,184, dated November 29, 1881, and do not desire to be understood as claiming any of the features of said invention, but only the improvements herein described and claimed.

Having thus fully described my said invention, what Iclaim as new, and desi'reto secure by Letters Patent, is-

1. In a saw-tempering apparatus, the combination, with the tempering-blocks, of supporting-plates provided'with flanges 0 along their edges, whereby 'a water-way is secured, substantially as shown and described. v
